Astronomy Picture of the Day Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2016 April 15 Graphene in space could hold clues to development of life on Earth An artist's concept of graphene, buckyballs and C70 superimposed on an image of the Helix planetary nebula (Image: IAC/NASA/NOAO/ESA/STScI/NRAO) Human beings may have only discovered how to create the one-atom-thick sheets of carbon atoms known as graphene in 2004 but it appears the universe could have been churning out the stuff since much earlier than that. While not conclusive proof its existence in space, NASA's Spitzer Space Telescope has identified the signature of graphene in two small galaxies outside our own. If confirmed, it would be the first-ever cosmic detection of the material and could hold clues to how carbon-based life forms such as ourselves developed.
Lindsey Caldwell « StyleLikeU I was drooling listening to Lindsey’s stories about her experience in Atlanta’s rich, underground music scene during the ’90s. She recalls what is now, sadly, an almost extinct phenomenon: sweaty nights of dancing at low-key clubs with ratty sofas, where people like Erykah Badu, Andre 3000, India Arie or Chilli might pop in and sing. Lindsey says, “Everyone wanted to know everyone… everything was a mix… it wasn’t pretentious.” For Lindsey, it was in this environment that she fell in love with drums and beats and rave and learned to be a skilled DJ, the kind with two turntables who knows how to blend songs and genres. In order to make her own imprint as a DJ, Lindsey moved to NYC with hundreds of vinyls in tow. It was while living on St.
Hubble data predicts Milky Way galactic collision When Galaxies Collide! It sounds like an early science fiction novel. However, analysis of Hubble measurements shows that our own Milky Way galaxy is moving toward a head-on collision with our nearest neighbor, the Andromeda galaxy (also known as M31). Double eclipse: Moment Moon AND International Space Station cross face of Sun By Daily Mail Reporter Updated: 20:58 GMT, 5 January 2011 Britons were only offered a clouded view of yesterday's partial solar eclipse owing to our typically dreary weather. But one lucky skywatcher in south-west Asia managed to catch a doubly striking glimpse of the natural phenomenon. After some careful calculations, photographer Thierry Legault decided to travel to just outside Oman's capital city of Muscat, where he knew he could catch both the Moon and the International Space Station briefly crossing the Sun.

Advertisting Radio telescopes capture best-ever snapshot of black hole jets An international team, including NASA-funded researchers, using radio telescopes located throughout the Southern Hemisphere has produced the most detailed image of particle jets erupting from a supermassive black hole in a nearby galaxy. "These jets arise as infalling matter approaches the black hole, but we don't yet know the details of how they form and maintain themselves," said Cornelia Mueller, the study's lead author and a doctoral student at the University of Erlangen-Nuremberg in Germany. The new image shows a region less than 4.2 light-years across -- less than the distance between our sun and the nearest star. Radio-emitting features as small as 15 light-days can be seen, making this the highest-resolution view of galactic jets ever made. The study will appear in the June issue of Astronomy and Astrophysics and is available online. Mueller and her team targeted Centaurus A (Cen A), a nearby galaxy with a supermassive black hole weighing 55 million times the sun's mass.
Interactive Biology Interactive Biology Serendip sees the web as a tool which can make education a more interactive and exploratory process, by making freely available educational resources at a variety of levels and also, even more importantly, be making it increasingly possible to learn by doing (see Serendip's web principles and credo on education and technology). To encourage understanding and use of the web in this way, Serendip provides annotated lists of links useful for learning/teaching in a variety of areas (see Interactive Physics and Interactive Chemistry).
